The large intestine of pig is cold in nature and sweet in taste, and has the functions of moistening intestine, removing lower energizer wind-heat and relieving frequent micturition.

The large intestine of the pig is delicious and can provide rich nutrition, but the large intestine of the pig can generate strong peculiar smell in a natural state or when the processing is not proper, and the large intestine of the pig has more folds and more stains, is not easy to clean and clean. And the pig large intestine contains more fat and cholesterol, is easy to become greasy due to improper processing, and also increases the risk of obesity. At present, people often use various chemical agents to clean the large intestine of the pig, and drug residues are easy to form. Secondly, the large intestine is easily polluted by microorganisms within the processing lag time, is easy to cause the propagation of the microorganisms and even cause food-borne diseases, and is a 'high-risk food' which is easy to cause food poisoning.
